Specification of Letters Patent.

Patented July 11, 1911.

Original application filed April 23, 1910, Serial N o. 557,144. Dividedand this application filed October 13, 1910. Serial No. 586,826.

To all 'whom it may concern:

Be it known that I, FREDERICK L. SAT- TLnY, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements in PneumaticStackers, of which the following is a specification.

My invention relates to improvements in pneumatic stackers, such forexample as is shown in my application Serial No. 557 ,144 of which thisis a division, and particularly to the chute therefor, which I amenabled to so adjustas to discharge and deflect material fromvariouspoints in its length, as may be desired, in a simple andexpeditious manner, as will be hereinafter more fully explained.

In the accompanying drawings, which form a part hereof, Figure l is aside elevation of a separator with a pneumatic stacker embodying myimprovements attached thereto; Fig. 2 a side elevation of a portion ofthe stacker chute; and Figs. 3 and 4 sectional views of the chut-e asseen from the dotted lines 3 3 and 4 4, respectively in Fig. l.

In said drawings the portion marked 10 indicates an ordinary separatorto which a pneumatic stacker straw chamber is attachable in any suitablemanner. Leading from the fan l2, mounted in said chamber, is the usualduct, 20, with which my improved chute, 30, communicates. Said chute 30is non-telescopic, and is vertically and horizontally adjustable, asusual, being mounted on a suitable turntable, as 31, and supported by ayoke, 32, and otherwise5'and adjusted by a windlass, 33, and wormedshaft operated by hand-wheel, 34, in an ordinary and well known manner.The outer under portion of said chute 30 is cut away a considerableportion of its length (Fig. l), and at its lower side I provide aguideway preferably composed of angle-bars, 36, (Fig. 4) having a space,37, therebetween. In said guideway I place a'slidable bar, 38, having agroove, 38, therein, which bar is movable by an endless chain or cable,39, attached to a lug, 40, on said bar, and which chain or rope passesabout sprockets or sheaves, as 4l, attached to the guideway,`and 42,secured to the chute, and is operable by means of a crank, 43,associated with sheave 42. To the outer end of said bar 38 a pair ofarms, 50, are secured, which lie on the outer side of the chute and arepreferably connected by a band, 51, to insure their stability, and inthe ends of said arms I mount a hood or deflector, 52, which travelsalong the inside of the chute, being indicated by full and dotted linesin Fig. l in its normal position, and which may be adjusted by means ofan arm, 53, to which is attached a cord, 54, running to withinconvenient reach of an operator. Also connected to said bar 38 I securea second pair of arms, 55, having rollers, 56, mounted in the endsthereof.

'Io the end of the lower portion of chute 30 I hinge a plurality ofhinged semi-cylindrical adjustable iller sections or closures, 60, whichare normally dependent from said chute, as indicated in Fig. l. By theemployment of the sectional fillers just described I am enabled toreadily adjust the stacker chute to discharge the material at differentdistances from the separator so that the same may be distributed over aconsiderable area and in such manner as to insure a compact stack, andwhich I accomplish in the following manner: As stated, the sections 60(Fig. l), and also the hood or deflector, are shown in normal position,and, when so arranged, material discharging through the chute willinstantly be deiiected downwardly upon striking the hood, which liesinside the chute. When it is desired to make the discharge slightlyfarther out, crank 43 is turned in the proper direction to cause chain39 to move bar 38 outwardly, during which outward movement the hood ordeflector 52, mounted on arms 50, is also carried the same distance, andalso, as will be readily understood upon reference to Fig. l, as saidbar 38 travels outwardly the arms 55 thereon carrying the rollers 56,against which the upper semicylindrical section GO rests, push each otsaid sections upwardly on its hinge, so that when the rollers havereached the outer end ot a section the latter has tilled up the openportion oi the chute to the extent ot its length, as indicated in Fig.2, and the closed portion ot' the chute becomes accordingly increased,the remainingv sections depending; trom the tirst section in like manneras it depends trom the chute by its hinged connection therewith; and assaid bar meets the hinge connecting said sections each hinge becomesseated in groove 8S thereof and is thus prevented trom lateraldisplacement during' the operation ot closing` or opening,` the chute.in this nianner the cut-away portion ot' the chute can be tilled step bystep as the bar 3S is caused to move outwardly, placingone section afteranother in position, while at the same time the same relation betweenthe outer end ot each section and the de'tleetor is constantlymaintained, and when all the sections have been tilled in the chute issubstantially a closed tube through its entire length, or to whateverextent said sections have been brought to closing position. lt will beunderstood also that said sections may be readily returned to dependentor normal position by reversing the direction ot movement oit bar 38,and the cut-away portion ot the chute thus enlarged as desired.

I claim as my invention:

l. The combination, with a pneumatic stacker, ot a vertically andhorizontally adjustable chute communieating,` with said tan and having aportion of its under side cut away, sectional tillers connected to saidchute, and means for raising and guiding` each oi said fillers intoposition to close said chute.
